Compositions and methods for reversibly dyeing soft contact lenses
Abstract:
A method and kit for producing reversibly dyed soft contact lenses. The contact lenses are submerged in saline solution and a dye is added to the saline solution, either directly or by means of a strip that has been impregnated with the dye. Preferred dyes include the common dyes sodium fluorescein, lissamine green, and rose bengal. After a period of time, the lens absorbs the dye and can be removed from the solution and placed on the eye. Once the lens is illuminated with ultraviolet light, it will glow or fluoresce. This creates a dramatic effect, particularly in dimly lit areas. The dyeing method does not utilize heat and thus is reversible. Soaking the lens in additional saline solution for a period of time will cause the dye to return to its non-dyed state.
